GAS OR 01L STOVE.

SPECIFICATION forming part of Letters Patent No. 635,841, dated October 31 1899.

Original application filed February 21,1899, Serial No. 706,375. Divided and this application filed May 19, 1899. Serial No.

To all whom, it may concern.-

Be it known that I, EDWARD BURDEN, engineer, a subject of the Queen of Great Britain and Ireland, and a resident of Desboro Villa, Dysart road, Grantham, in the county of Lincoln, England, have invented certain new and useful Improvements in and Relating to Gas or Oil Stoves, (for which I have made application for Letters Patent in Great Britain, No.12,434, bearing date June 2, 1898,) of which the following is a specification, this application being a division of my application serially numbered 706,375, filed February 21, 1899.

. My invention relates to stoves, and has for its object to provide a stove in which the air to support combustion is initially heated to secure perfect combustion and a stove in which effective provision shall be made for inducing circulation of air, so that thereby warm air shall be disseminated throughout the apartment in which the stove is placed.

My invention consists in the arrangement and design of a gas or oil stove hereinafter described, and particularly set forth in the claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of a stove made in accordance with my invention, and Fig. 2 is a section corresponding thereto on the line a b.

In carrying my invention into effect in the provision of a gas or oil stove, as illustrated in the drawings, I provide a casing E, formed in two partsa base E and a body E mounted thereon. YVithin the exterior stoneware casing is fitted a circular double metal casing E F, within which there is an annular space through which air passes in from orifices Y, issuing out from orifices Y to the burner-chamber F. The double casing E F is formed with a central aperture f, within which is supported a flue-tube I. Between the exterior of the casing E F and the exterior stoneware casing E are lateral or annular spaces E up which air may pass from orifices 0 provided in the base E The upper part of the exterior stoneware casing E is of less diameter than its lower part and is lined on the interior with a tube E whose base is'perforated and secured to the top of the casing E F and contacts at its upper extremity with a retaining-plate E, by which the upper end of the flue-tube I is held.

It will be understood that the air to support combustion partly passes up the passages E and partly down the orifices Y to the burnerchamber, thence centrally upwardly through the flue-tube I.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A gas or oil stove consisting of a central burner-chamber a flue-tube supported by the burner-chamber for the interception and regular distribution of heat, and an outer casing'surrounding such central burner-chant her and an'annular perforated guard super posed above the central burner-chamber and extending to the outer casing for guiding the upwardly-issuing air-currents to the center substantially as described.

2. A gas or oil stove consisting of a double casing the central portion of which forms the burner-chamber while the annular portion forms a passage for air, suitable orifices be ing provided-at the upper part of the exterior and at the lower part of the interior thereof, such double casing having a flue-tube superposed thereupon and a perforated air=tube surrounding it and a perforated top-support= ing plate carried by the flue-tube and joining the air-tube, the Whole being enveloped in an outer casing between which and the double casing a space is provided for the upward pas= sage of air substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDWARD BURDEN,
